FYI, JPEW has a proposed patch here

http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=jpew/reproducible&id=d091d2aa53ea417f70c10f5ce89151820c3db9ce

for allowing a recipe to just set SOURCE_DATE_EPOCH directly.

But maybe that currently is at odds with SOURCE_DATE_EPOCH being in 
BB_HASHBASE_WHITELIST ?
